Intro and ending title screens (Lightroom Classic's Titles panel): each on
or off, a background colour and, centred, the Overlays identity plate or a
line of text, in the plate's colour or an override colour, at a scale, for
its own duration (default: the slide duration).
- Playback timeline: titles are items (Item::Title) of Playback; the intro
plays once before the first photo, the ending after the last photo when
repeat is off; random order never moves them; arrows step across them;
fades, pause and readiness work as for slides; n of N counts photos only.
- Engine: slide_title (TitleSettings in prefs.json, TitleCompose drawing
through the slide composer and overlay text renderer), slideshow.titles
get/set, slideshow.preview {title}.
- UI: titles composed on a render worker (Renderer::request_title), the
control bar shows Intro / End, Settings > Slideshow > Titles section and
a Photo / Intro / Ending preview choice; strings in the nine locales.
- Docs: parity row (partial), playback note, whats-new, control and MCP.
